Cygnus X-3 is a well known microquasar which produces radio flares, up to
20 Jy, which are associated with relativistic jets from this source. Over
the last several years SMA observations have been preformed as part of
international multi-wavelength observing campaigns of the major flaring
activity in Cygnus X-3. In this presentation I will show some of the results
of these campaigns and examine what the SMA can tell us about the physics of
the jets in this system. I will also discuss the discovery of Cygnus X-3's
"little friend" and how combining data from Chandra (X-ray) and SMA has lead
to a more accurate distance estimate to Cygnus X-3. Finally I will note some
tantalizing possibilities with future observations with the Event Horizon
Telescope.
